Constantly facing a rising demand for 3D printable superalloy materials from automotive, aerospace and industrial sectors, Digital Metal® has developed and launched two new superalloy grades. These 3D printable superalloys can be used in extreme operating conditions.
Digital Metal, manufacturer of high-precision binder jetting technology systems, has named these new grades as DM 247 and DM 625. Its binder jetting technology makes it highly suitable for 3D printing superalloys, including non-weldable grades, with near full density.
3D Printable Superalloys
Superalloys are basically metals which exhibit high strength and high corrosion resistance. They can undergo high heat and stresses to still emerge strong. Such unique properties are in demand for applications in automotive, aerospace and chemical industries. So far, non-weldable metal materials were difficult to be 3D printed but with Digital Metals’ binder jetting technology, this can be made possible.
Digital Metal has rigorously tested its new 3D printable superalloys successfully. The DM 247material is based on the non-weldable MAR M247, which is widely used as material for turbine blades and in other applications with elevated temperatures.
The DM 625 is an Inconel 625-grade. Its application areas range from seawater applications and chemical processing equipment, to nuclear industry and aerospace.
Digital Metal Binder Jetting Technology
Digital Metal is known for manufacturing binder jetting 3D printers and its technology is a perfect fit to 3D print superalloys as it helps avoid most of these problems by printing in an ambient temperature without applying any heat, followed by a separate sintering step. During sintering densification takes place without melting and with minimal thermal gradients during cooling from sintering temperature.
[penci_blockquote style=”style-3″ align=”none” author=”Ralf Carlström, General Manager at Digital Metal” font_style=”italic” uppercase=”false”]“We have been receiving qualified requests for these materials from various large companies. Many producers within the aerospace and automotive business have long been anticipating high-quality superalloys that are suitable for 3D printing. Now we can offer them the perfect combination – our unique binder jetting technology and superalloys that are specially developed for our printers.”[/penci_blockquote]
Digital Metal will cater to the rising demand for 3D printable superalloys and aim to capture the industrial markets which demand these new materials. Both have undergone extensive in-house testing to ensure they meet the customers’ expectations.
